When the Conduit tool is selected, the Modify | Place Conduit tab provides options for placing conduit.
Justification. Opens the Justification Settings dialog where you can specify Horizontal Justification, Horizontal Offset, and Vertical Justification for the conduit.
Automatically Connect. Lets you automatically connect to the snaps on a component when starting or ending a conduit segment. This option is useful for connecting segments at different elevations. However, when drawing conduit at a different offset or to disable snapping to an non-MEP element, clear Automatically Connect to avoid making an unintentional connection.
Tag on Placement. Applies the default annotation tag to a conduit segment when it is placed in the view.
